(CNN) -- It's a tough time for businesses, but one entrepreneur may have found the recipe for success.

Male and female servers go topless at Grand View Topless Coffee Shop.

On Monday, Donald Crabtree opened Grand View Topless Coffee Shop in Vassalboro, Maine, where the waiters and waitresses serve their customers topless.

In a town with fewer than 4,500 residents, the topless coffee shop is booming with business. Paul Crabtree, the owner's brother, describes business so far as "fantastic."

"It's just been crowds mobbing in," he said.

Donald Crabtree faced initial opposition to his plan, but he won the right to go ahead in a planning board hearing last week. Many local residents were irate over the idea of combining coffee and nudity. Crabtree, however, saw a profitable business venture.

"I know what people want," he said. "People like nudity, and coffee is profitable. Sure, I'd start a coffee shop, but I'd be out of work in a week."
